Answer:
<u>-1133</u>
Step-by-step explanation:
<u>Formula for nth term</u>
<u>Finding d</u>
- d = -45 - (-28)
- d = -45 + 28
- d = -17
<u>Solving for a₆₆</u>
- a₆₆ = -28 + 65(-17)
- a₆₆ = -28 - 1105
- a₆₆ = <u>-1133</u>
First you need the size of an angle QPR = B = 180° - 123°
Lenght of QP = 10cm
QR = x
QP = r
x² = r² + r² - 2r² × cosB
Answer: 12 hours and 24 Minutes
Step-by-step explanation:
7*60 = 420
810/420 = 1.9285
93- 100 = 53-60
subtract 40 from 93.
1.53*8 = 12.24
Answer: 12 hours and 24 Minutes
Answer:
a. The initial value is 5575
b. The decay factor is 0.35 or 35%
Step-by-step explanation:
The decay equation is given as;
y = 5575(0.65)^t
Mathematically, a decay equation can be written in the form;
A = Ir^t
where A is the amount at a time, I
is the initial value and r represents the decay rate
a. So by comparing this with what we have, we can see that the initial value is 5575
b. We want to write the decay factor
We can rewrite the equation as;
y = 5575 (1-0.35)^t
where 0.35 = 35/100 which can be said to be 35%
